Application led August 16, 1904:. Serial No. 220,965.

lie it known that Unseren A. VILsoN, a citizen ot' the United States.residing at Pleasant Vallev, in the county of Fairfax and State ot'7irginia, have invented certain new and useful Improvements in SawmillSet-Vilorlts, et"

which the following is a specification.

The invention relates to ar. improvement in sawmill set-works, andparticularly to a manually-operated type ol" novel structure andarrangement.

rlhe main object of the invention is to provide manually-operable meansfor adjusting' the log-knees in either direction with relation to thesaw and at variable speed..

The invention, broadly stated, com prehends a knee-adjusting shaftcarryirg a tiXed gear, speed and reversing gears arranged for operativeengagement with said shaft, and means to operate said latter gears atwill in the movement of the lever.

The details of the preferred embodiment ot' my improved set-works willoe fully described in the Yfollowing speciication and are clearly shownin the accompanying drawings, in which- Figure l is a perspective viewoi a set-works constructed in accordance with my invention. Fig. 2 is anenlarged longitudinal central section of the same. Fig. 3 is an enlargedhorizontal section ot the same, taken just above the knee-adjustingshaft. Fig. d is perspective details ot' the pawls and operating-arm forthe main gear. Fig. 5 is a broken plan bottom, showing the operating endot the anxiliary handle. Fig. 6 is a perspective ot one ot the stops forlimiting the operation of the set-works. Fig. i is a perspective viewot' the pawl-litting arm.

Referring to the drawings, wherein like rei'- erence-numerals indicateiilte parts throughout the several views, my improved set-workscomprises a iranie l, arranged to be secured to a suitable rail Zot asaw-carriage. The trame is preferably ot' metal and comprisesbars 3 anda, secured to project at right angles and beyond the edge of the rail 2,as shown. One bar, 3, is formed with an arc-shape extension 5, theperiphery of which is 'formed with a series of holes 6 to receive stops7. rEhe holes are preterably arranged in two or more rows, the holes otlone row beingintermediate the holes ol adjoining' row, whereby to securevariable adjustments. rlhe stops T are ot a size and shape to limit themovement of the mechanism, as here-- inatter described, being providedwith depending pintles 8 toenter any ot' the holes S. rrihe forward stopis provided with a transverse voperating set-screw Q for a purposehereinafter (,lescribed.

The knee-adhisting shatt l() is revoiubly supported in the arms 3 and e.beingarraizged parallel with the carriage-rail Z and provLded at one.end with means for moving the logknees. (Not shown.) @n lthe shaft l),between the arms 3 and di, is [ixedly secured a main gear 1l, andcontiguous this gear ind loose upon extensions '10 l0" et' the bearings10b are arranged the speed-gear l2 and the reversing-gear 13. Thesegears are preferably arranged one cach side the main and in closerelation thereto.

A. series et pawls lo arepivot(- d between the arms 15 ot' the lever with their tree endsarranged for operative engagement with the main gear li, these pawlsbeing pret'- erably arranged in plural number rather thai'.

'a single paw! to insure a certainty of action,

some ot' the pawls being mounted on shaft i8 and some on shat't 2l,hereinafter mentioned. A second pawl 1T is aise mounted on the shaft 18,which pivotally supports some of the pawis 1G, this pawl l? beingarranged for engagement withfthe main gear in a direction reverse tothat oi pawi 16. fr pawl i9 also mounted on the shaft 2l., with itsoperative end arranged for engagement with the reversing-gear 1.3. A.pawl 20, pivotally niiounted upon a s ia'tt 21, secured intermediate thearms 15, is arranged ter operative engagement with ed-gear t'. n3 andQ-t are arranged in horizontal alinernent across the rear of theset-works,the shafts being respectively mounted in the bars 3 and e.intermediate the arms shaft is pro fided with lixed pinion 25, arrangedto artis '78 @a i mesh with the speed-gear t), the oud ot shaft 23beyond the bnr il being' provided with :t

ineshes with the pinion '51, lieved u pon the adk justing-shalt it).

A set oi pawls 3Q are mounted intermediate the bars irl and et withtheir ends ei'igag'- ingthe main gear-i l, wherebty to preventoverrunnine' or baclnvard movement oi said gear.

To provide tor th i suitable manipulation of the various pawls to obtainthe object desired, i provide rods 33 and Sel, the former beine'arranged to control the operation o' the revereine-gear, while thelatter controls the operation olf the speed-gear. The arm E3 is providedat its lower ends with a loop-torm terminal 35, which passes beneath theshaft l() and upwardl),v to the pawl i9, honig there bent at a rightangle` as at 36, to mulcrlie said pawl. The crown oi' the loop 35 restsupon one end oi a liiting'nrni il?, pivoted between the bars 3 and et,with its opposite end ui'iderlvixigl the lree ends oi the pa 'ls 52.Adjacent the pawl-shal't 1U the red 33 is prof vided with alaterally-extendine' stud 38, which engages a lil-'ting-u rm 3i), which:i rm is pivotalliY mounted upon shalt itl and has a transverse bar L10,which underlies the pawl i6 lorward ol their pivots. The rear end olEpawl i7 is notched at il to receive the bar lit).l whereby upwardmovement ot said har ILO will li"'t the pawls iii from engagement withthe main gear l1 and at the same time torce the pawl 1'? into eng;gement with said gear. 'lhe lower end ot' rod ist is connected to arearward extension of the pn wl llh whereby an upward movement ot' saidrod will torce the pawl 2() into engagement with the siieecl-g'ezir l2.lhe upper ends or' tl e rods 33 :1nd Het ere connectedtooperating-handlcs '72 and 13, respectivelif1 having bent lowertermiuffils, as shown, und pivotallv supported on a stud 41st, arrangedtransversely of the lever liniear the handle end ot' the latter. ,lfhchandles are held in certain pilsitions in the normal condition or theparts through the medium of spring 45 and e6., respectively, the formeroi: which isarranged to hold the rod inthe extreme ot upward movement,while the latter is arranged to hold the rod ML in the ex#A treme ol"downward movement, this being' the normal position of the parts. in thisnormal position the rod 33 beine' elevsted will heid the pawl 1Q out oienge versinlewenr, the crown oi the loop 35 out of 'erneut with the reiContact with the lifting-2111113?, und the trausverse bar Ail) ot' thelifting-arm 3 9 out ot' engagement with the pawls itt while the rod willmaintain the pawl 20 out of engagement with the speed-gear lli).

An arm /ti' projects laterali;y from the lever iiq riding` in closeproximit,7 to the peripher),7 et the extension 5, serving to limit themovement ot the lever in both directions by contact with the stops 7'.

Assuming the parts inl normal position` the operation ot' the set-works'is as follows: A reciprocatory movement ol." the handle end ot' leverist will turn the main gear 1l by means of the pawls 16, thus advancingthe gear and tui-nine` the adjustine-shaft l0, and thereby adjust]nelthe log-knees connected to the shaft l0. ,lt it is desired to reversethe movement ol shaft l0., the handle 412 is depressed or swung downwardon its pivot against the tension et' spring;l 45g which movementdepresscs rod 33, elevating pawls 16 by lifting'- arin 39, forcing thebacking-pawls out ot' engag'eu'ient with gear il through movement et thelifting-arm Si" and permitting pawl i9 'to engage the reversing-gear 13.A reciprocatorv movement of the lever will now advance or turn thereversing-gear foi-wurd, (h'ivimg pinion Q8 and Z9 on shaft 2411rearward and th rough the idler 30 driving pinion Bl. rearward. itspinion 31 fast on shat't 10, said shaft will be revolved in a directionreverse to its movement under inliuence of the main gear ii. Bvreleasing1 the pressure on the handle lf2 the spring C5 operates toreturn all parts to normal position, as will be evident. 'ilo acceleratethe speed of shat't lO beyond that possible by lgear 1i, i elevate rod34 b v swinging' handle t3 on its pivot, which eleva ion of the rodi'orces pawl 2O into coperation with the speed-gear l2. Reciprocatorymovement of the lever ist will revolve the gear lf2, turning' thepinions 25 and 26 on the shaft Z3 and through the latter turning' pinion27, and hence shalt i0. As pinion 25 is considerabl;7 smaller than gearl2 and pinions 2G end 27 the same size, it is evident the shaft i0 willbe more rapidl5v revolved than when actuated by the main gear li. Therecirn'ocntoi-,iT movement or throw otl lever 14j is limited by its arm4T contacting with the stops L which latter may be adjusted in holes 6to secure any desired length of stroke, a further adjustment to limitthe throw of the lever between adjacent holes being' secured by propersetting oi screw 9, will. be evideut.

To permit proper operation of the parts Vtrom the side oli theSaw-carriage opposite to that on which the set-works is mounteeh iprovide a pull-rod L18, pivoted at t9 to the lever le near the upper endand having' a stirrup-hanijlle 50. A rod 5l, having' a stirruphandheld52, is lixed at one end to handle 452 above its pivot, whereby pull onthe rod will suitably operate rod A second rod having a handle end 54e.,is connected to hanbeingr at the limit oi' its downward movement i die4:3 and arranged to operate rod 34C whe IOO forced inwardly. Thehandheld 52 is mounted within the handle of the pull-rod 4:8, while theend 54: of rod 53 is turned upward at a right angle a slight distancebeyond said handle 50, whereby rod 5l may be operated by a pull and rod53 by pressure without releasing the handle of the pull-rod a8. Theoperation of the set-works by use of the pullrod is fully apparent, itbeing understood that such pullrod and connected parts may be of anylength desired to position them convenient to the operator.

The fixed gears and pinions may be keyed to the shaft; but I prefer touse the ordinary set-screw attachment in connection with the groove inthe shaft.

It will be noted that the operative throw of the lever is in the samedirection during the direct or reverse movement of shaft l0, thedifference in direction being gained by manipulating the pawlsdescribed.

I do not wish to be understood as limiting myself to the preciseconstruction herein shown and described, as I consider all obviouschanges of structure and arrangement as within the scope and spirit ofmy invention.
